Code viewer for World: Complete Infinite World
//==============================================================================
//  Welcome to the Infinite world !
//==============================================================================

// This program was made by Nathan Bonnard.
// In this world, you can generate an infinite world ! 
// But this isn't really infinite, it would be impossible, 
// the world do a simple loop when the player reach the border. Like in real life !
// This world isn't a kind of game with specific goal, just enjoy the landscapes and all objects !
// 
// The first purpose of this world was to create an exploration world to just enjoy good views and the fact that it is infinite 
// Finally it became a sort of Minecraft, I wanted to create that type of game but with complex 3D Objects, not cubes.
// I wanted to demonstrate the power of javascript and Three.js : we can create big world with a lot of objects even in a browser
// Also, the aim is to encourage people using the first person view on worlds or the sun that you can find on Enhanced World.
// If you want to change the world by yourself, it would be a bit hard to get into 2000 lines of code, 
// but you can simply change some letiables and see the effects. Here are those letiables :

//------------------------------ TWEAKER BOX ------------------------------//

const squaresize = 5 ; // The world is like a infinite grid of square. squaresize is the size of a square
var MOVESPEED = 7; // Speed of the player

var viewDistance = 2; // determinate the maximum distance to see ground (viewDistance * squaresize * groundMultiplier)
var groundMultiplier = 551; // The world is divided by zone (grounds) that size groundMultiplier*squaresize
var worldSize = 13; // dimension of the world, it is not really infinite but big and can loop. There is worldSize * worldSize Grounds 

const SKYDISTANCE = 3000; // Distance of stars and sun
const NBSTARS = 100; //number of stars

//Where all textures and objects are
const PATHTEXTURES = "/uploads/meak/";

//Limit between rare and small objects (in term of size, obviously here a castle size is bigger than 4 but a rock is not)
//Care it depends on the squaresize letiable. If you increase squaresize, you should also decrease this letiable
const limitSizeForRareObjects = 2;

//Number of maximum element that can be pose in each ground. You can change this after running the world
var maxElementsForest = 300;
var maxElementsSnow = 90;
var maxElementsSand = 60;

//Determine if the world can or not generate different type of ground. You can change this after running the world
var enableSand = true;
var enableSnow = true;
var enableForest = true;

//Path of sounds that are played during the game depending on what type of ground you are walking on
const SOUNDFOREST = "/uploads/meak/forestsound.mp3";
const SOUNDSNOW = "/uploads/meak/snowsound.mp3";
const SOUNDSAND = "/uploads/meak/sandsound.mp3";
const SOUNDNIGHT = "/uploads/meak/nightsound.mp3";

//Objects that are loaded for each type of ground. Add some Objects that you found on the internet and see !
//For that it need to be an Object3D (.obj) with a material (.mtl).
//If the material need some texture, upload those textures too.
